Courierit poor customer experience

I purchased a parcel from Telkom(Smartbroadband) & the router was to be delivered at my place of residence.This made sense at the time as I was still on leave.The whole process delayed,mainly due to Telkom & eventually my parcel was dispatched.I got a call at about 07:20 (13/01/16) in the morning from Courierit stating that they will deliver my parcel today (13/01/16).I obviously told them that I was at work & won't be able to accept the parcel.A new address was given(my place of employment),I received no word from Courierit for the next 2 days.Saturday(16/01/16),I give them a ring stating that I would like to personally pick up the parcel where it is being stored (JHB).Lady(refused to give her name) who attended to me stated I couldn't collect the parcel as its not a weekday.As an auditor,I move from one client to the next & I requested to change the delivery address to PTA where I'll be working, gave her the address & when I failed to provide a landline to the address,she refused to use my mobile number as the contact number, stating they need the landline.At this point,she was raising her voice.Courier IT is providing a service & now tarnishing the name of Telkom in the process.
